During the series' run, two vomics (voice comics) were released, and an anime adaptation was featured on the children's variety show Oha Suta.

Hana's nosebleed occurs whenever her she sees potential in others, and she uses it to scout five boys: Kiri Kurose, Rei Shinozuka, Junpei Akamatsu, Kazuhiko Midorikawa, and Yugo Aoyagi.

To reach their goal of becoming the top idol group, with the help of Hana, Crash gains experience through singing, acting, and dancing.

Yui Sakura, Kazuhiko's childhood friend, becomes Hana's assistant in managing the group at White Star on his recommendation.

Fujiwara created the series due to the growing popularity of idols in media, and she had based all members of Crash on characters from her previous works.
